Issue with selectpicker version 1.13 in Bootstrap 4: selected option's content not properly displayed

The issue at hand is purely aesthetic: the select element does not align properly with the selected option. It appears too low and extends beyond the container. Additionally, the caret is displayed in the top right corner instead of the middle right where it should be. Visually, it looks like this:

https://i.sstatic.net/onPgm.png

Here is the code snippet causing the problem:

<select class="selectpicker" data-style='btn-primary'>
    <option value="value">I'm a sad and a little bit too long option</option>
</select>

While the select dropdown itself displays correctly, the button (initial field displaying the selected value) appears distorted for unknown reasons. It seems likely that the plugin itself may be causing the issue, as minimal external styling is being applied. I am seeking advice on how to resolve this so that the plugin functions properly, as I prefer using existing tools over custom coding solutions. My CSS skills are limited, making it challenging to decipher the underlying causes. Upon inspecting the generated HTML by the plugin, it seems that the parent container (div.filter-option) lacks certain properties necessary to position the content correctly (the text-containing element div.filter-option-inner) and manage its appearance.

Plugin source (purportedly compatible with Bootstrap 4): https://github.com/snapappointments/bootstrap-select/releases/tag/v1.13.0 Bootstrap version used in Laravel 5.6: default build-in with Laravel 5.6 - Bootstrap 4.0. I appreciate any assistance, guidance, or analysis on addressing this issue! Thank you in advance!

<select class="selectpicker" data-live-search="true">
<option data-tokens="ketchup mustard">Hot Dog, Fries and a Soda</option>
<option data-tokens="mustard">Burger, Shake and a Smile</option>
<option data-tokens="frosting">Sugar, Spice and all things nice</option>
</select>

Works perfectly when executed in a fresh jsfiddle environment, yet when embedded in a custom local (and online) .html file, the rendering remains faulty. The cause behind this discrepancy eludes me completely!

Answer №1

After a long struggle to pinpoint the issue, I finally uncovered the root cause of this unexpected behavior buried deep beneath the surface. * drum roll * The culprit turned out to be the omission of <!DOCTYPE html> at the beginning of my html page's response. Surprisingly, this seemingly minor detail was wreaking havoc on the plugin's functionality (yet bizarrely not impacting any other aspect of the page). The ironic twist in this tale lies in the use of Laravel for view management, where a complex system of sections and stacks was seamlessly loading resources and content. The blunder originated from a tiny oversight within a snippet of html code—a lone <style> tag lingering at the bottom of my .blade.php file, stubbornly remaining after the @endsection directive. This led Laravel to prioritize its display over the contents of the section tag, causing it to dominate the rendered document on my home view. What a journey! Grateful for all the assistance provided!

Answer №2

To achieve a dropdown size equal to the select element, you can apply the following CSS:

.bootstrap-select {
  position: relative !important;
}

.bootstrap-select .dropdown-menu {
  right: 0 !important;
}

.bootstrap-select .dropdown-menu li a span.text {
  white-space: initial !important; 
}

$('.selectpicker').selectpicker();
.bootstrap-select {
  position: relative !important;
}

.bootstrap-select .dropdown-menu {
  right: 0 !important;
  transform: translate3d(0, 37px, 0px) !important;
}

.bootstrap-select .dropdown-menu li a span.text {
  white-space: initial !important; 
}
