Is there any method to call store selector inside phtml file? I found only store switcher but I need store selector multiselect options.
I ended up with simple solution.
I copied file
app/design/adminhtml/default/template/sotre/switcher.phtml to my
phtml file, then I just put
multiple="multiple" into select tag and did some other tiny changes.
I also created own block which extends
Mage_Adminhtml_Block_Store_Switcher to get a list of already selected websites.
In this way I transformed store switcher into store multi-select.
