## Horizontal Menu View
|
|
A horizontal menu view supports displaying a list of times on a screen horizontally (side to side, in a single row) similar to a lightbox.
|
|
|
|
## General Information
|
|
|
|
Items can be selected on a menu via the cursor keys, Page Up, Page Down, Home, and End, or by selecting them via a `hotKey` - see ***Hot Keys*** below.
|
|
|
|
:information_source: A horizontal menu view is defined with a percent (%) and the characters HM, followed by the view number (if used.) For example: `%HM1`
|
|
|
|
:information_source: See [Art](../general.md) for general information on how to use views and common configuration properties available for them.
|
|
|
|

|
### 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, C: 2, D: 3 }
|
|
hotKeySubmit: true
|
|
```
|
|
This would select and submit the first item if `A` is typed, second if `B`, etc.
|
|
|
|
### Items
|
|
|
|
A horizontal menu, similar to other menus, take a list of items to display in the 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", "Third Item"]
|
|
```
|
|
|
|
## Example
|
|
|
|
|
|
|
|

|
|
<summary>Configuration fragment (expand to view)</summary>
|
|
<div markdown="1">

|
```
|
|
HM2: {
|
|
focus: true
|
|

|
|
submit: true

items: [
|
|
"prev", "next", "details", "toggle queue", "rate", "help", "quit"
|
|
]
|
|
}
|
|
```
|
|
</div>
|
|
</details>
