below is code:
var sceneToolbar = { view:"toolbar", id:"sceneToolbar", height:40, cols: [ {view:"select", width:160, value:"Textured", options:["Textured", "Wireframe"]}, ] };
i want the “Textured” show in the left in horizonal and center in vertical.
and how to add checkbox before the select’s popup menu item? thanks.
It is already looks left and centered for me 
If you want to have it smaller that toolbar, you can set padding to toolbar view or custom height for the input

As for checkbox, you can adjust the template of richselect control, but it will require some extra coding to make it really functional.

You can look at the next component, here you can use datatable with checkbox column
