Glossary Realtime Filter

[Woodsy]

I have got a glossary list showing and am trying to add a dropdown filter and keyword search. The list is being pulled from a HubDB. I am trying to make the dropdown (column from HubDb called 'category2' and keyword search both update the list in realtime rather than having to press a submit button. Would anyone be able to let me know how I would implement the filter? Thank you in advance for any help.

You can first retrieve and display all rows when rendering the page by including "data-*" attributes on each row. This would look something like this:

<div>
  <h3>Filter by category:</h3>
  <select id="category-filter">
    <option value="show-all">Show all</option>
    {% set rows = hubdb_table_rows(module.hubdb_id) %}
    {% set categories = rows | map(attribute='category2') | unique %}
    {% for category in categories %}
      <option value="{{ category }}">{{ category }}</option>
    {% endfor %}
  </select>
</div>

<div>
  <h3>Search by keyword:</h3>
  <input type="text" id="keyword-search" placeholder="Enter keyword...">
</div>

<div class="row-fluid a-z">
  {% for letter in alphabet %}
    <h3 id="{{ letter }}" class="letter">{{ letter }}</h3>
    <ul class="word">
      {% for row in rows %}
        {% if row.name is string_startingwith letter %}
          <li 
            data-category="{{ row.category2 }}" 
            data-name="{{ row.name | lower }}">
            <a href="{{ request.path }}/{{ row.hs_path }}">{{ row.name }}</a>
          </li>
        {% endif %}
      {% endfor %}
    </ul>
  {% endfor %}
</div>

And you can do something like this in javascript:

document.addEventListener('DOMContentLoaded', function() {
    const selectCategory = document.getElementById('category-filter');
    const inputKeyword   = document.getElementById('keyword-search');
    const items     = Array.from(document.querySelectorAll('.word li'));

    function filterList() {
      const chosenCategory = selectCategory.value;
      const keyword = inputKeyword.value.trim().toLowerCase();

      items.forEach(li => {
        const category  = li.dataset.category;
        const name = li.dataset.name;
        const matchCategory = (chosenCategory === 'show-all' || category === chosenCategory);
        const matchKeyword  = (keyword === '' || name.includes(keyword));
        li.style.display = (matchCategory && matchKeyword) ? '' : 'none';
      });
    }

    selectCategory.addEventListener('change', filterList);
    inputKeyword.addEventListener('input', filterList);
  });

This is untested. Adapt this to your code.

Hi @Woodsy, I hope that you are well!
 

Thanks for asking the HubSpot Community!

I spotted these threads, not sure if that's entirely similar to what you are looking for but it might be interesting for you to take a look:

- The solution from @alyssamwilie on this post "Passing HubDB Multi-selection select options into Module Field Choice option"
- The solution from @alyssamwilie on this post "Choice field / select a row from HubDB list within a custom module"

Also, I'd love to put you in touch with our Top Experts: Hi @jonchim, @matt_scott and @Stephanie-OG do you have suggestions to help @Woodsy, please?

Have a fantastic day and thanks so much in advance for your help!
