Search element (dropdown element, 100% width on the input it self)
We do use a input field with a search element of Metronic Theme 8. Vue.
<input type="text" class="form-control form-control-lg form-control-solid px-15" name="search" placeholder="Search" data-kt-search-element="input">
<div class="menu menu-sub menu-sub-dropdown menu-column p-7 w-325px w-md-375px show" data-kt-menu="true" id="kt-search-menu" data-popper-placement="bottom-end"></div>
Now you can set the width by:
w-md-375px. What we want to achieve is that the menu dropdown, should always 100% (same width) as the input field. Check the attachment what we want to achieve. Important, that this will work on each device.
Can't edit my answer (looks like a bug). Please check attachment: https://ibb.co/wybhNWW
The dropdown element is a separate element that does not depend on the input width so the input width and dropdown width should be set separately. As a workaround you should set the input width equal to the dropdown with.
