Quasar 
Option Group
The Quasar Option Group component is a helper component, which allows you to better control the grouping of binary (as in on or off, true or false, 1 or 0) form input components like checkboxes, radios or toggles. A good usage for this component is for offering the user a set of options or settings to turn on and off, and thus the name of the component.
Works well with QField for additional functionality such as a helper, error message placeholder and many others.
Basic Usage
Example on a group of checkboxes:<template>
<q-option-group
color="secondary"
type="checkbox"
v-model="group"
:options="[
{ label: 'Option 1', value: 'op1' },
{ label: 'Option 2', value: 'op2' },
{ label: 'Option 3', value: 'op3' }
]"
/>
</template>
<script>
export default {
data () {
return {
// `v-model` binded to `group`,
// which must be an array for checkboxes and toggles
group: ['opt1']
}
}
}
</script>
Example on a group of radios:<template>
<q-option-group
color="secondary"
type="radio"
v-model="group"
:options="[
{ label: 'Option 1', value: 'op1' },
{ label: 'Option 2', value: 'op2' },
{ label: 'Option 3', value: 'op3' }
]"
/>
</template>
<script>
export default {
data () {
return {
// `v-model` binded to `group`,
// which must be a String when using radios
group: 'opt1'
}
}
}
</script>
Vue Properties
Supports v-model, which is required. For “radio” type it must be a String, otherwise (“checkbox” or “toggle” type) your scope variable binded to v-model must be an Array.
| Vue Property | Type | Description |
|---|---|---|
type | String | The type of input component to be used. The default is radio. The other choices are checkbox and toggle. |
options | Array | An array of objects with value and label properties. The binary components will be created according to this array. |
color | String | One from Quasar Color Palette. |
left-label | Boolean | When set to true, the labels will be put on the left side. |
inline | Boolean | Adjusts the display of the binary components fill out the row, instead of being stacked vertically. |
disable | Boolean | When set to true, the binary components are not selectable thus cannot change your v-model. |
Vue Events
| Vue Event | Description |
|---|---|
@change | Fired when the component model changes. |
@focus | Fired when the component gets focus. |
@blur | Fired when the component loses focus. |
Other Examples
A group of radios with different colors.<q-option-group
type="radio"
v-model="group"
:options="[
{ label: 'Option 1', value: 'op1' },
{ label: 'Option 2', value: 'op2', color: 'secondary' },
{ label: 'Option 3', value: 'op3', color: 'amber' }
]"
/>
And a group of toggles, but not stacked vertically when possible. We add inline Boolean property.<q-option-group
inline
type="toggle"
v-model="group"
:options="[
{ label: 'Option 1', value: 'op1' },
{ label: 'Option 2', value: 'op2' },
{ label: 'Option 3', value: 'op3' }
]"
/>
You would normally also add this component inside a QField component as shown below.<q-field
icon="cloud"
helper="Choose your option"
label="Pick something"
:error="hasError"
error-label="Select at least one option"
>
<q-option-group
type="radio"
v-model="group"
:options="[
{ label: 'Option 1', value: 'op1' },
{ label: 'Option 2', value: 'op2' },
{ label: 'Option 3', value: 'op3' }
]"
/>
</q-field>
