### Conditional disabled state
Similar to `visible` property, it is possible to control the `disabled` state with the following scenarios:
- direct value of `boolean` type
- binding to a property of the `boolean` type
- binding to a property of the `Function` type that evaluates condition and returns `boolean` value
#### Using direct value of boolean type
```html
<content-action
target="all"
title="Action for 'custom' node"
[disabled]="true"
(execute)="runCustomAction($event)">
</content-action>
```
#### Using a property of the boolean type
```html
<content-action
target="all"
title="Action for 'custom' node"
[disabled]="shouldDisableAction"
(execute)="runCustomAction($event)">
</content-action>
```
The markup above relies on the `shouldDisableAction` property declared at your component class level:
```ts
export class MyComponent {
@Input()
shouldDisableAction = true;
}
```
#### Using a property of the Function type
```html
<content-action
target="all"
title="Action for 'custom' node"
[disabled]="isCustomActionDisabled"
(execute)="runCustomAction($event)">
</content-action>
```
The code above relies on the `isCustomActionDisabled` property of a `Function` type declared at your component class level:
```ts
export class MyComponent {
isCustomActionDisabled = (node: MinimalNodeEntity): boolean => {
if (node && node.entry && node.entry.name === 'custom') {
return false;
}
return true;
}
}
```
Code above checks the node name, and evaluates to `true` only if corresponding node is called "custom".
Please note that if you want to preserve `this` context within the evaluator function,
its property should be declared as a lambda one:
```ts
funcName = (parameters): boolean => {
// implementation
return true;
}
