Multiselect V18 is a free grouped dropdown snippet for choosing options under a separate selection cap for each group. Its example uses states, and Colorlib says the options can be adapted. The page does not specify the numeric cap or establish that it can be changed, so check the actual V18 demo or download before relying on a particular limit.
How Multiselect V18 works
V18 divides dropdown options into groups and limits the number of selections within each group. That differs from a single overall cap: each category has its own allowance. The default example is organized around states, but Colorlib says the options can be adapted to other choices.

The feature description does not state the number allowed per group, whether the cap is configurable, or the V18-specific JavaScript API. Those implementation details are not established by the collection overview.

What the snippet is built with
Colorlib describes its multiselect collection as plain HTML, CSS, and vanilla JavaScript, with no jQuery, Bootstrap files, or plugin dependency. It says the snippets can run independently or in Bootstrap 4, 5, and 6 projects. This is collection-level guidance, not a verified inspection of V18’s individual source code.

When a per-group cap makes sense
This pattern can suit a long set of choices that naturally falls into categories, when users need to select several items but should not exceed a category-specific maximum. Grouping can make a long list easier to navigate; the cap can keep selections within an intended boundary.
Make the rule visible before someone interacts with the dropdown. For example, describe the limit in the field label or group instructions. If a user reaches the cap and another click appears to do nothing, an unexplained rule can look like a broken control.

Check the trade-offs before choosing it
| Decision | What to consider |
|---|---|
| Grouped or flat options | Groups can help with very long lists when categories are meaningful. A flat list may be simpler for a short set. |
| Per-group or global cap | V18 is described as applying a separate limit to each group. The exact maximum and whether it is configurable are not stated in the collection description. |
| Finding choices | The roundup describes live search in V10–V13 and V20, and jump-to-letter typing in V16. These are alternatives in the collection, not stated V18 features. |
| Reviewing selected choices | The roundup describes removable tags in V02 and V19, and a count after four displayed names in V14. It does not establish that V18 uses either treatment. |
| Input method and accessibility | Test keyboard and screen-reader behavior, and confirm that controls are usable on touchscreens. The roundup recommends these checks but does not establish V18’s accessibility conformance. |
What to test before using it
Because the available description does not establish V18’s exact limit, API, browser support, or accessibility conformance, verify those details against the actual demo or downloaded implementation before integrating it.
- Confirm the maximum for each group and whether it can be configured.
- Check that the interface explains the cap and makes it clear when it has been reached.
- Test the expected interaction with a keyboard: open the list, move through options with the arrow keys, toggle an option with Space, and close with Escape. These are checks recommended by Colorlib, not verified V18 behavior.
- Test with a screen reader and on a phone or other touch device.
- Verify how selected items are displayed, removed, and submitted by your application.
License and reuse
Colorlib states that its snippets are free for personal and commercial use under CC BY 3.0 if the credit link is retained. Check the terms accompanying the specific V18 download before reuse, since the collection description alone does not verify the download’s applicable terms.
