# Custom link properties
The link definition property template can be used to add a custom property of link type. When defining a link property, the following fields can be used:
Definition properties
| Field | Description |
| --- | --- |
| type | This field is optional for links. Can be either string, integer, number, array or boolean.
Information noteThe link effect is achieved by defining the component field to "link", see below. |
| component | Used for defining how the property is visualized in the property panel. Used to override the default component that comes with the type setting.
This field is mandatory for a link property and should always be "link". |
| label | Used for defining the label that is displayed on the link. |
| url | Used for defining the web address used in the link. |
Information noteLinks are always opened in your default web browser when clicked.
## Example
### Defining a custom button
Defining a custom property of link type can look like below.
Example:
Information noteCustomization of properties always start with items:.
```
define( [
],
function ( ) {
return {
definition : {
type : "items",
component : "accordion",
items: {
settings: {
uses: "settings",
items: {
MyLink: {
label:"My Link",
component: "link",
url:"http://www.qlik.com/"
}
}
}
}
},
paint: function ($element) {
//add your rendering code here
$element.html( "props-link" );
}
};
} );
```
This is what it looks like in the property panel
