How do I set the initial value of a combo that is in a form? I wanted to set it to the first value.

The combo is embedded in form using connector.

The initial value for this is set to " "

{type:"combo",name: "category_id", label:"Product Group", labelWidth:150 ,inputWidth:200 ,connector: "product_list/form_combo"},

There is a parameter ’ selected=“true” ’ to select one on the values or you need to get combo and apply methods setValue or setComboText
