Please see the [`<b-form-select>` `options` prop](/docs/components/form-select#options-property)
93-
docs for details on the formats and helper props associated with `options`.
92+
`options` can be an array of strings or objects. Available fields:
93+
94+
- **`value`** The selected value which will be set on `v-model`
95+
- **`disabled`** Disables item for selection
96+
- **`text`** Display text, or **`html`** Display basic inline html
97+
98+
`value` can be a string, number, or simple object. Avoid using complex types in values.
99+
100+
If both `html` and `text` are provided, `html` will take precedence. Only basic/native HTML is
101+
supported in the `html` field (components will not work). Note that not all browsers will render
102+
inline html (i.e. `<i>`, `<strong>`, etc) inside `<option>` elements of a `<select>`.
103+
104+
<p class="alert alert-danger">
105+
<strong>Be cautious</strong> of placing user supplied content in the <code>html</code> field,
106+
as it may make you vulnerable to

112+
113+
<!-- eslint-disable no-unused-vars -->
114+
115+
```js
116+
const options = ['A', 'B', 'C', { text: 'D', value: { d: 1 }, disabled: true }, 'E', 'F']
117+
```
118+
119+
If an array entry is a string, it will be used for both the generated `value` and `text` fields.
120+
121+
You can mix using strings and [objects](#options-as-an-array-of-objects) in the array.
122+
123+
Internally, BootstrapVue will convert the above array to the following array (the
124+
[array of objects](#options-as-an-array-of-objects)) format:
125+
126+
<!-- eslint-disable no-unused-vars -->
127+
128+
```js
129+
const options = [
130+
{ text: 'A', value: 'A', disabled: false },
131+
{ text: 'B', value: 'B', disabled: false },
132+
{ text: 'C', value: 'C', disabled: false },
133+
{ text: 'D', value: { d: 1 }, disabled: true },
134+
{ text: 'E', value: 'E', disabled: false },
135+
{ text: 'F', value: 'F', disabled: false }
136+
]
137+
```
138+
139+
### Options as an array of objects
140+
141+
<!-- eslint-disable no-unused-vars -->
142+
143+
```js
144+
const options = [
145+
{ text: 'Item 1', value: 'first' },
146+
{ text: 'Item 2', value: 'second' },
147+
{ html: '<b>Item</b> 3', value: 'third', disabled: true },
148+
{ text: 'Item 4' },
149+
{ text: 'Item 5', value: { foo: 'bar', baz: true } }
150+
]
151+
```
152+
153+
If `value` is missing, then `text` will be used as both the `value` and `text` fields. If you use
154+
the `html` property, you **must** supply a `value` property.
155+
156+
Internally, BootstrapVue will convert the above array to the following array (the
157+
[array of objects](#options-as-an-array-of-objects)) format:
158+

160+

```js
162+
const options = [
163+
{ text: 'Item 1', value: 'first', disabled: false },
164+
{ text: 'Item 2', value: 'second', disabled: false },
165+
{ html: '<b>Item</b> 3', value: 'third', disabled: true },
166+
{ text: 'Item 4', value: 'Item 4', disabled: false },
167+
{ text: 'Item 5', value: 'E', disabled: false }
168+
]
169+
```
170+
171+
### Changing the option field names
172+
173+
If you want to customize the field property names (for example using `name` field for display
174+
`text`) you can easily change them by setting the `text-field`, `html-field`, `value-field`, and
175+
`disabled-field` props to a string that contains the property name you would like to use:
176+
177+
```html

200+

201+
{ item: { d: 1 }, name: 'Option D' }
202+
]
