    copied!<p>I wanted to achieve a similar thing, so I took a look at the typeahead code and hacked something together, see the below:</p> <p>Its still is a bit buggy with handling placeholders and closing the dropdown when you click away, but this gives me a toggle button that I can click that is a sibling to my input element, and it fetches the full list from the dataset instead of a small suggestion list.</p> <p>Example html (I am using custom typeahead data-bindings for knockout, but you get the idea):</p> <pre><code> &lt;div class="col-md-12 input-group tt-dropdown-group"&gt; &lt;input id="category" name="category" type="text" class="form-control" data-bind=" attr: { placeholder: categoryCaption }, typeahead: categories, typeaheadValueKey: 'Name', typeaheadValue: category, typeaheadDestroy: true" /&gt; &lt;span id="category-drop" class="input-group-addon tt-dropdown-icon"&gt; &lt;span class="glyphicon glyphicon-chevron-down"&gt;&lt;/span&gt; &lt;/span&gt; &lt;/div&gt; </code></pre> <p>Example javascript using jQuery:</p> <pre><code> $(".tt-dropdown-group .tt-dropdown-icon").on("click", function() { var $input = $(this).parent(".tt-dropdown-group").find("input.tt-query"); var $toggleBtn = $(this); // these are all expected to be objects so falsey check is fine if (!$input.data() || !$input.data().ttView || !$input.data().ttView.datasets || !$input.data().ttView.dropdownView || !$input.data().ttView.inputView) { return; } var ttView = $input.data().ttView; var toggleAttribute = $toggleBtn.attr("data-toggled"); if (!toggleAttribute || toggleAttribute === "off") { $toggleBtn.attr("data-toggled", "on"); $input.typeahead("setQuery", ""); if ($.isArray(ttView.datasets) &amp;&amp; ttView.datasets.length &gt; 0) { // only pulling the first dataset for this hack var fullSuggestionList = []; // renderSuggestions expects an suggestions array not an object $.each(ttView.datasets[0].itemHash, function(i, item) { fullSuggestionList.push(item); }); ttView.dropdownView.renderSuggestions(ttView.datasets[0], fullSuggestionList); ttView.inputView.setHintValue(""); ttView.dropdownView.open(); } } else if (toggleAttribute === "on") { $toggleBtn.attr("data-toggled", "off"); ttView.dropdownView.close(); } </code></pre>
