Display calculation caption on button hover

user23793 · July 2, 2025, 7:12pm

There is a Window called “caption” in calculation & fiel where you can add some information. That info is written below the main topic or calculation. You allready tried to minimize that by offering a much smaller text. But it would be way better if people like me could use the “caption” field and the option to hide the text behind a small “info” button like that . Position of that should be behind the main topic/calculation in the right top corner … like m². By tapping or mouse over effect on the info, the text will appear and the whole calc is way easier to read. Looking forward to see it. Dimitri

Hi there, @user23793

Interesting idea, thanks for sharing! If more users support this request, we’ll try to think it over in the future.

As for now, our devs will be happy to create a custom solution for you. I’ve forwarded your request to them and let you know once it’s done

Hi there, @user23793

This code should be added to the Custom JS field on the Settings tab of your widget’s settings:

const INFO_LIST = ['Eigenkapital', 'Monatliche Kosten ⁉️'];

function listener(selector, callback) {
  const target = document.querySelector(selector);
  if (target) return callback(target);

  const observer = new MutationObserver(() => {
    const node = document.querySelector(selector);
    if (node) {
      observer.disconnect();
      callback(node);
    }
  });

  observer.observe(document.body, { childList: true, subtree: true });
}

function normalizedString(str) {
  return str.toLowerCase().trim();
}

function createElement(tag, options = {}) {
  return Object.assign(document.createElement(tag), options);
}

function createInfo(size) {
  const container = createElement('div', {
    className: 'result-info-container',
    style: `
      display: flex;
      align-items: center;
      justify-content: center;
      opacity: 0.7;
      font-size: ${Math.floor((size * 2) / 3)}px;
      width: ${size}px;
      height: ${size}px;
      border: 1px solid rgb(17, 17, 17);
      border-radius: 50%;
    `
  });

  const block = createElement('div', {
    className: 'result-info',
    textContent: 'i'
  });

  container.appendChild(block);
  return container;
}

function mapResultBlocks(container) {
  const resultList = container.querySelectorAll('[class^="result"]');
  const map = new Map();

  for (const block of resultList) {
    const isSecondary = block.className.includes('secondary');
    const labelWrapper = (() => {
      if (isSecondary) {
        return block.querySelector(
          '[class*="result-secondary__SecondaryLabel-sc"]'
        );
      }
      return block;
    })();

    if (!labelWrapper) continue;

    const label = labelWrapper.firstElementChild;
    const caption = labelWrapper.lastElementChild;
    const labelText = label?.textContent;

    if (!labelText) continue;

    const value = (() => {
      if (isSecondary) {
        return block.querySelector('[class*="result-secondary__Value-sc"]');
      }
      return block.querySelector('[class*="result-primary__Value-sc"]');
    })();

    map.set(normalizedString(labelText), {
      label,
      container: block,
      caption: label === caption ? null : caption,
      value,
      isSecondary
    });
  }

  return map;
}

function attachHoverBehavior(value, infoSize) {
  let isHovering = false;
  let isTouched = false;

  const { value: valueNode, caption, container, isSecondary } = value;
  if (!caption || !valueNode) return;

  const info = createInfo(infoSize);
  valueNode.appendChild(info);

  valueNode.style.display = 'flex';
  valueNode.style.alignItems = 'center';

  if (isSecondary) {
    const animatedValue = valueNode.querySelector(
      '[class*="animated-number__Content-sc"]'
    );
    const hiddenValue = valueNode.querySelector(
      '[class*="result-secondary__HiddenValue-sc"]'
    );
    if (animatedValue) animatedValue.style.position = 'relative';
    if (hiddenValue) hiddenValue.style.display = 'none';
    valueNode.style.minWidth =
      parseInt(window.getComputedStyle(valueNode).minWidth || '0') +
      infoSize +
      'px';
    valueNode.style.justifyContent = 'end';
  }

  container.style.position = 'relative';
  container.style.overflow = 'unset';

  caption.style.cssText = `
    margin-top: 0;
    display: none;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    background-color: #fff;
    z-index: 2;
    opacity: 1;
    padding: 8px 12px;
    border-radius: 4px;
    box-shadow: 0px 2px 8px 0px #00000040;
  `;

  function show() {
    isHovering = true;
    caption.style.display = 'block';
  }

  function hide() {
    isHovering = false;
    setTimeout(() => {
      if (!isHovering) caption.style.display = 'none';
    }, 100);
  }

  valueNode.addEventListener('mouseenter', show);
  valueNode.addEventListener('mouseleave', hide);
  caption.addEventListener('mouseenter', show);
  caption.addEventListener('mouseleave', hide);

  valueNode.addEventListener('touchstart', (e) => {
    e.stopPropagation();
    isTouched = !isTouched;

    if (isTouched) {
      show();
    } else {
      hide();
    }
  });

  document.addEventListener('touchstart', (e) => {
    if (!valueNode.contains(e.target) && !caption.contains(e.target)) {
      isTouched = false;
      hide();
    }
  });
}

listener('[class*="results__Container-sc"]', (container) => {
  const mappedBlocks = mapResultBlocks(container);

  INFO_LIST.forEach((title) => {
    const value = mappedBlocks.get(normalizedString(title));
    if (!value || !value.value) return;

    const fontSize = parseInt(
      window.getComputedStyle(value.value).fontSize || '14'
    );
    const infoSize = Math.floor(fontSize / 2);

    attachHoverBehavior(value, infoSize);
  });
});

In the 1st line, you should add the calculation names where the captions should appear on hover:

Please try it out and let me know if you like the result

user23793 · July 5, 2025, 5:33pm

Hi,

it works almost perfectly. Small things to adjust…

the hover Info should be connected to the title, not to the result.
if using the view of „secondary result“, the i hover button is way to small.
works only in the „calculations“ not in „ fields“
But in general it’s a cool calc!!!

Hi there, @user23793

Thank you for the feedback!

I’ll discuss with the devs if it’s possible to adjust the first 3 points you’ve mentioned

A post was split to a new topic: Dynamic field caption

Hi there, @user23793

Here is a final solution with the requested adjustments:

const WIDGET_SELECTOR = '.elfsight-app-8fc0c5c7-3987-491f-a48b-1703f4ba3566';
const INFO_LIST = [
  'Zu versteuerndes Einkommen',

function listener(selector, callback) {
  const firstTarget = document.querySelector(selector);
  if (firstTarget) {
    return callback(firstTarget);
  }

  const observer = new MutationObserver((_, observer) => {
    const targetNode = document.querySelector(selector);
    if (targetNode) {
      observer.disconnect();
      callback(targetNode);
    }
  });
  observer.observe(document.body, { childList: true, subtree: true });
}

function createElement(tag, options) {
  return Object.assign(document.createElement(tag), options);
}

function normalizedString(string) {
  return string.replace(/\s+/g, '').toLowerCase();
}

function installStyles() {
  return document.head.appendChild(
    createElement('style', {
      innerHTML: `
        .result-info-container + .tooltip-wrapper {
          display: none;
        }

        .result-info-container:hover + .tooltip-wrapper,
        .result-info-container:focus + .tooltip-wrapper,
        .result-info-container:active + .tooltip-wrapper {
          display: block;
        }

        .result-info-container + .tooltip-wrapper:hover,
        .result-info-container + .tooltip-wrapper:focus,
        .result-info-container + .tooltip-wrapper:active {
          display: block;
        }
      `
    })
  );
}

function createInfo(size) {
  const container = createElement('button', {
    tabindex: '0',
    className: 'result-info-container',
    style: `
      display: flex;

      border-radius: 50%;
      margin-left: 8px;
      background: transparent;
    `
  });

  const block = createElement('div', {
    className: 'result-info',
    textContent: 'i'
  });

  container.appendChild(block);
  return container;
}

function getDescriptionSelector(type) {
  return {
    primary: '[class*="result-primary__PrimaryContainer-sc"] > :nth-child(3)',
    secondary: '[class*="result-secondary__SecondaryLabel-sc"] > :nth-child(2)',

function getDescription({ type, node }) {
  const selector = getDescriptionSelector(type);

    const description = getDescription({ type, node });
    console.log(description);

      return;
    }

    const size = parseInt(window.getComputedStyle(node).fontSize);
    const infoBlock = createInfo(size);
    node.appendChild(infoBlock);
    node.style.display = 'inline-flex';
    node.style.alignItems = 'center';

    description.style.cssText = `
      opacity: 1;
      padding: 8px 16px;
      margin-top: ${(size + 8) * (type === 'field' ? 2 : 1)}px;
      background-color: #fff;
      box-shadow: 0px 2px 8px 0px #00000040;
      border-radius: 8px;
    `;

    const tooltipWrapper = createElement('div', {
      className: 'tooltip-wrapper',
      style: `
        position: absolute;
        top: 0;

    }

    container.style.overflow = 'unset';
  });
});

Please try it out and let me know how it worked

Hello max,

sorry for late answering…holidays. I tried and so far ist allmost perfect, check yourself … comlicated calc reduced to only 4 sliders … great tool, thank you! Dein U | VILLAGEU

Max · July 30, 2025, 2:19pm

Great, thank you so much for the feedback!

You said it’s almost perfect — is there anything specific in the widget’s design you’d like to tweak?

If so, just let us know the details, and we’ll do our best to make it happen
