What I mean to say is try with 100% of anchor. If you observe any change
in width of the the selection field, adjust anchor value to yours 150
px. To verify it, create a field of xtype textfield below or on above of
it. Give width 150px to the textfield and compare with selection
xtype.http://dev.day.com/docs/en/cq/5-6/widgets-api/index.html?class=CQ.form.Selectionhttp://dev.day.com/docs/en/cq/5-6/widgets-api/index.html?class=CQ.Ext.layout.AnchorLayout
