## Toggle Menu View
A toggle menu view supports displaying a list of options on a screen horizontally (side to side, in a single row) similar to a [Horizontal Menu](horizontal_menu_view.md). It is designed to present one of two choices easily.
## General Information
Items can be selected on a menu via the left and right cursor keys, or by selecting them via a `hotKey` - see ***Hot Keys*** below.
:information_source: A toggle menu view is defined with a percent (%) and the characters TM, followed by the view number (if used.) For example: `%TM1`
:information_source: See [MCI](../mci.md) for general information on how to use views and common configuration properties available for them.
### Properties
| Property | Description |
|-------------|--------------|
| `textStyle` | Sets the standard (non-focus) text style. See **Text Styles** in [MCI](../mci.md) |
| `focusTextStyle` | Sets focus text style. See **Text Styles** in [MCI](../mci.md)|
| `focus` | If set to `true`, establishes initial focus |
| `submit` | If set to `true` any `accept` action upon this view will submit the encompassing **form** |
| `hotKeys` | Sets hot keys to activate specific items. See **Hot Keys** below |
| `hotKeySubmit` | Set to submit a form on hotkey selection |
| `argName` | Sets the argument name for this selection in the form |
| `items` | List of items to show in the menu. Must include exactly two (2) items. See **Items** below. |
### Hot Keys
A set of `hotKeys` are used to allow the user to press a character on the keyboard to select that item, and optionally submit the form.
Example:
```
hotKeys: { A: 0, B: 1, Q: 1 }
hotKeySubmit: true
```
This would select and submit the first item if `A` is typed, second if `B`, etc.
### Items
A toggle menu, similar to other menus, take a list of items to display in the menu. Unlike other menus, however, there must be exactly two items in a toggle menu. For example:
```
items: [
{
text: First Item
data: first
}
{
text: Second Item
data: second
}
]
```
If the list is for display only (there is no form action associated with it) you can omit the data element, and include the items as a simple list:
```
["First item", "Second item"]
```
