How may I use a multiselect field in the Impresspages Plugin options. Something like this:
{
"label": "Social Nets",
"name": "socialNets",
"type": "select",
"multiple": "multiple",
"default": "",
"values": ["", "facebook", "twitter", "pintrest"]
}
Of course, the field above "multiple" doesn't work in this code snip. So, how to implement it in the plugin options json file?
