Variable in HTML drop down menu

Issue

i need to create an HTML drop down menu with option variable based on external list.

i'm tryng with:

set item_list [$var]
<select> 
<option value="$item_list">$item_list</option> 
<option value="$item_list">$item_list</option> 
<option value="$item_list">$item_list</option> 
<option value="$item_list">$item_list</option> 
<option value="$item_list">$item_list</option> 
</select>

but what i obtain is all option in this way

{volvo saab opel audi}

Any suggest?

Solution

Manually creating the HTML code is one option:

set item_list {volvo saab opel audi}
set html_code "<select>"

foreach item $item_list {
    append html_code "<option value=\"$item\">$item</option>"
}

append html_code "</select>"

puts $html_code

However, there are other template processing packages described here. Since you didn't describe your use case in greater detail, this should suffice.
