Multiple field visibility was not working properly while using
Multiple Checkbox field as visibility condition. Only "is equal to"
and "is not equal to" was implemented for Multiple Checkbox. The
"is equal to" uses formData.get which only retrieves the first
value from Multiple Checkbox. The Multiple Checkbox was not having
"contains" option which was already available for some other
fields.
This commit will implement "contains" for all the input types
which comes under hidden_condition_no_text_opt in the file
s_website_form.xml. These include radio, checkbox and Multiple
Checkbox. The fields which comes under hidden_condition_no_text_opt
which does not require multiple inputs can use "contains" and
"doesn't contain" interchangeably with "is equal to" and
"is not equal to"
