Supported External Dashboard Widget Attributes
The following external dashboard widget attributes are supported:
string—Can be used for JSON.
tracker—A single tracker can be selected. The selected project is passed to the third-party widget application with the specified name: "{trackerFieldName}-projectId".
trackerList—Multiple trackers can be selected. This generates a project selector for itself. The selected project is passed to the third-party widget application with the specified name: "{trackerFieldName}-projectId".
project—A single project can be selected.
projectList—Multiple projects can be selected.
The values of the attributes are passed to third-party widget application in JSON format.
The following example shows the JSON configuration that is passed to the third-party widget application:


{

"someText": "lorem ipsum dolor",

"trackerId": [

4870

],

"trackerId-projectId": [

4

],

"trackerId2": [

4612

],

"trackerId2-projectId": [

3

]

}

The keys come from the extension configuration JSON, except for the projectIds which are linked to the tracker attributes.
