Parameters use
model
Controls the selected value of the input. The value needs to be one of the provided via options:
Attention!
If you hardcode this value, it will not be reactive and the selection won't change. Use a variable instead and, ideally, a closed loop.
config
The config parameter is used to set the shape of the input between lined and shaped. Being omitted will render the default line shape.
label
The label parameter is used to set the text label of the component. Make sure you always use it.
Can also use the label slot:
help-text
The help-text parameter is used to provide additional assistance to the user.
name
The name parameter is used to set the name of the component. This is useful when the component is part of a form.
options
The options attribute is an array of objects that represent the chips. Each object inside the array should have the following properties:
text: The text that will be displayed inside the chip.value: The value of the option.disabled: A boolean that indicates if the chip is disabled.
We can use <option> tags to define the values of options
The content con the options can be customized using the slots with the pattern options-<option-value>:
And combining both approaches:
Code
INFO
Notice in this last example that the label takes the value from the <option> inner text and not from the slotted content.
Flags
readonly
The readonly parameter is used to set the input in a read-only state. It's commonly used to display information.
disabled
The disabled parameter is used to block the interaction with the component. Not to be confused with readonly.
required
The required parameter is used to set the component as required.
invalid
The invalid parameter is used to set the component as invalid.
The default text adapts to the localization:
with-search
The with-search parameter is used to apply an internal search feature to filter the available options.
You can change the label of the search using search-placeholder.
The input emits a search event that can be used for external filtering.
Methods
reset()
We can all the reset() method of the WebComponent in order to reset the value. This will clean the internal states and emit the nullable value with the change event, plus a restarted event:
In this example, the button triggers the method:
