Only advanced elements can be modified using Selective User Interface framework, basic elements can only be changed using `showHUD` SQF command.
## 1. Config Values
### 1.1 Adding an element
```cpp
class ACE_UI {
class elementName {
idd = 300; // IDD of display where the element is located
elements[] = {3000, 3001}; // List of control IDCs of the elements to toggle (some can have background as a separate control, this allows grouping them together)
location = 0; // Location where the element is present (0 - anywhere, 1 - ground only, 2 - vehicle only)
// Custom conditions base class (read below)
class conditions {};
};
};
```
### 1.2 Setting an existing element
```cpp
class ACE_UI {
class elementName {
// Custom conditions of where the element can be visible, each condition has its own entry (use prefixes for easy identification and prevention of overwriting)
// As soon as one condition returns `false` the element will be hidden, this can be included when adding a new element
class conditions {
my_source = "vehicle player == 'B_Heli_Attack_01_F'"; // Condition which makes the element visible only when player is in `'B_Heli_Attack_01_F'` vehicle.
};
};
};
```
## 2. Scripting
Adding new elements through scripting is currently not possible.

2 | Element Name | String | Required
3 | Show/Hide | Boolean | Optional (default: `false`)
