Autocomplete
Bootstrap 5 Autocomplete component
Autocomplete component predicts the words being typed based on the first few letters given by the user. You can search the list using basic scroll and the keyboard arrows
Note: Read the API tab to find all available options and advanced customization
Basic example
The filter
option is required in order for component to work properly. The option
accepts a function that is expected to return an array of results or a
Promise
that resolves to an array of results.
Display value
The displayValue
option allow to separate oryginal result value from the value
that will be displayed in the result list or input (after selection). Its useful when the data
returned by the filter
function is an array of objects. You can specify which
parameter of the object should be displayed.
Asynchronous search
The function passed to the filter
option can return a Promise
that
resolves to an array of results. By default the component expects to receive data as an array
of strings. If you want to return an array of objects instead, you can use
displayValue
option to specify which parameter should be used as a display value
of the specific result.
Threshold
Use threshold
option to specify a minimum number of the characters in the input
field needed to perform a search operation.
Custom item template
The itemContent
option allow to display custom HTML in the result list. You can
use the listHeight
option to modify the result list height when you want to
display more content in the component dropdown.
Custom content
A custom content container with a class .autocomplete-custom-content will be displayed at the end of the autocomplete-custom-item-subtitle dropdown. You can use it to display a number of search results.
