BuddyPress.org

i have same need.
is there any plugin to make more advanced profile fields??

another thing i need is when people select for example country from a combobox next combobox load cities of that country so he can select city of country.

any plugins?

I found a way to hide the list if they didn’t choose the suggested number but ideally I would like it to give them a pop up notification that you can only select 5 instead of just being listed in the description under the box.

javascript:

function checkboxlimit(checkgroup, limit){
	for (var i=0; i<checkgroup.length; i++){
		checkgroup[i].onclick=function(){
		var checkedcount=0
		for (var i=0; i<checkgroup.length; i++)
			checkedcount+=(checkgroup[i].checked)? 1 : 0
		if (checkedcount>limit){
			alert("You can select a maximum of "+limit+" boxes.")
			this.checked=false
			}
		}
	}
}		
checkboxlimit(document.forms.your_form_name_or_id['field_name[]'], 5);
