Actions with elements
When the user taps the card, action calls the event specified in url
.
{
"actions": [{
"log_id": "<unique_id>",
"url": "div-action://<action_description>?other/parameters"
}]
}
Parameter |
Description |
|
An event that is triggered by tapping the card. |
|
Logging ID. It must be unique within a single card. |
You can open the menu by tapping using the special menu_items
parameter. If at least one action in the array has a menu_items
field, tapping the element will show a menu, and all other fields will be ignored.
A separate type of action are actions that are triggered only by a long tap (longtap-actions
).
Sets of states
The state element switches the appearance of content. You can use it to add:
- Buttons that change their state (for example, the like icon when tapped).
- Content that can be expanded (for example, a bridge card or a geo block).
One picture changes to another, but the user sees it as an interaction.
To switch to a different state, use url
:
div-action://set_state?state_id=<div_data_state_id/div_id/state_id>&temporary=<bool>
The path is formed from the hierarchy root:
