I have one more question for you.
I have a drop list and want to preselect one value from it.
Right now I create a map ("Item1", "0")("Item2", "1")("Item3", "0"), pass it to witz and use $if to preselect position.

<select name="MyList"> 
	$for(i in MYLIST)
		$if ( i != 0 )
			<option value="$i._key" selected="selected">$i._key</option>
		$else
			<option value="$i._key">$i._key</option>
		$/
	$/
</select>

I'm not aware of any other simple way, I do it like this too. Only alternative I know about is sending MYLIST as an array of arrays/maps of two field, where the second contains the "selected=\"selected\"" or empty string, so it can be included in single pass, without $if. But it seems to me even worse, because it pushes html code into app Smile

Is there a shorter way (without $if)? Maybe something similar to c?

$for(i in MYLIST)
	<option value="$i._key" $(i != 0) ? selected="selected" : "">$i._key</option>
$/

I believe (can't test right now) you can inline the $if:

$for(i in MYLIST)
	<option value="$i._key" $if(i != 0) selected="selected" $/>$i._key</option>
$/
