Its Select documentation covers styling a native <select> with .form-select, and it does not provide checkbox lists, removable tags, or search inside a dropdown. If you need those behaviors, you build them yourself with plain HTML, CSS, and JavaScript, and that is what the examples in Colorlib’s September 28, 2026 article, “24 Bootstrap Multiselect Dropdown Examples (No Plugin) 2026,” demonstrate. Colorlib states that the examples use no jQuery, no Bootstrap JavaScript files, and no third-party plugin.
The useful question is not which example looks best but which interaction fits your list length, your selection rules, and your form submission. This guide walks through those decisions and the points that break in production.

What Bootstrap 5.3 does and does not provide
Bootstrap’s Select documentation for v5.3 describes one mechanism for dropdowns: applying a class to a native element. In its words:
Free tools Windows power users keep installed
One-click scans. No signup required.
“Custom
<select>menus need only a custom class,.form-selectto trigger the custom styles.”
The same documentation notes that these custom styles cannot modify <option> elements because of browser limitations. The result is that Bootstrap changes the look of the closed control, not the behavior of its list. A checkbox list, a tag-based picker, or a searchable dropdown is therefore a custom interface, not a Bootstrap class you can add to a select.
That distinction matters for the rest of this article. Every pattern below either keeps a native <select> underneath and syncs it, or replaces the list with custom markup. Those two approaches have different accessibility and form-submission consequences, covered in the sections that follow.
What the Colorlib collection covers
Colorlib’s headline counts 24 examples. Its implementation notes refer to 20 dropdown variants, numbered V01 through V20, and the page also includes four further multiple-choice layouts: topic tiles, filter checkbox groups, feature checkboxes, and an availability grid. Read the count as Colorlib presents it, and check the numbering against the page when you download the code.

| Simple checkbox list with select all | Multiselect V01 |

| Grouped choices | V08, V18 |
| Selection limits | V17, V18 |
| Country or state lists and compact summaries | V14 to V16 |
| Other multiple-choice layouts (topic tiles, filter checkbox groups, feature checkboxes, availability grid) | Four layouts listed separately from the dropdown variants |
Choosing a pattern by list size and task
Start with the number of choices, then add the other constraints. Colorlib’s guidance on list length gives a practical starting point:
Rank #3
| Choices | Suitable pattern | Reason |
|---|---|---|
| About seven or fewer | Checkboxes or tiles | Every option stays visible, so users compare without opening a menu. |
| Long lists | Live search | Users type a few characters instead of scrolling. |
| Very long lists | Grouped choices or jump-to-letter behavior | Categories and letter shortcuts make the list scannable. |
Three further axes change the choice even within one size band:
- Whether categories matter. If options belong to clear groups, a grouped pattern (V08 or V18) preserves that structure.
- Selection limits. If you cap the number of picks, you need a pattern that counts and enforces them (V17 or V18).
- How many selections are visible. Removable tags (V02, V19) work for reviewing a modest number of selected values. When many values are selected, a count in the closed control keeps the form compact. A tag list that grows to dozens of items becomes harder to scan than the count it replaces.
Before you pick, also decide whether the form must submit values through a real form field. Colorlib says its dropdowns keep a real <select> under the custom interface and write choices back to it. If your back end reads standard form submissions, that retained field is the main reason to prefer these examples over a purely visual widget.
Reading the selected values
Colorlib’s article gives a short JavaScript expression for collecting selected values from the underlying select:

One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchconst values = Array.from(select.selectedOptions).map(o => o.value);For a PHP form, the article notes that a field name ending in square brackets, such as topics[], makes the submitted values arrive as an array. A minimal read on the server looks like this:
$topics = $_POST['topics'] ?? [];Test both lines against your own markup. Colorlib presents them as the way its examples work; they have not been validated against every Bootstrap version or form framework.
Stating selection limits before users reach them
Colorlib’s examples include a seven-choice cap and per-group limits. A cap that appears only when the user tries to select an eighth item is a failure of instruction. Put the rule in the field label or the helper text next to the control, for example “Choose up to seven topics.” Keep the limit and the enforcement in sync: if the label says seven, the widget should refuse the eighth selection and say why.
Keyboard, screen reader, and touch checks
Colorlib recommends testing any custom widget with a keyboard and a screen reader. The keyboard sequence it suggests is:
- Tab to the control and open the list.
- Move through options with the arrow keys.
- Toggle the highlighted option with Space.
- Close the list with Escape.
Native <select multiple> behaves differently on desktop: users typically hold Ctrl on Windows or Linux, or Cmd on macOS, to add non-adjacent options by clicking. If you replace the native list with checkboxes or tags, your own sequence must work without that convention. Check touch targets on phones as well, since small checkbox rows and tag close buttons are common failure points. For how the native element is defined, see MDN’s reference for the select element.
Licensing before reuse
Colorlib states that its snippets are free for personal and commercial use under the CC BY 3.0 license, provided the credit link is kept. Confirm the license text on the download page at the time you use the code, because terms can change and the credit requirement applies to the snippets as Colorlib distributes them. If you modify the markup heavily, keep the attribution wherever the license requires it.
