I thought this might need to be the solution. The issue is the children are set up as a Static Resource, where the content field appears to be the file.
something like that would maybe possible with a MIGXdb TV grid instaed of a collection and file TV inputtype for the content field with a dynamic path in the mediasource
The only way to achieve this, that I can think of, is to create a custom plugin (event = “OnManagerPageBeforeRender”) that adds some code to override the component MODx.panel.Static with Ext.override and changes the function “getMainFields” to add a source-parameter.
...
Ext.override(MODx.panel.Static, {
getMainFields: function(config) {
var its = MODx.panel.Static.superclass.getMainFields.call(this,config);
its.push({
xtype: 'modx-combo-browser'
,source: 3 //add the desired media-source-id
...
});
return its;
}
});
...
I’m not sure I would recommend such an approach though.
