expecting eList is an int variable you can check if the current item that will be listed is the last item that should be listed and add ^n at the end of his name. i think this is the best option to add a blank in the menu
PHP Code:
public Menu_Frontend(id)
{
new menu = menu_create("\yWhat da dog doin?", "Menu_Backend");
new szLine[17], szData[4];
for(new i; i < eList; i++)
{
formatex(szLine, charsmax(szLine), "%i", i);
formatex(szData, charsmax(szData), "#%i", i);
if(i == eList - 1) add(szLine, charsmax(szLine), "^n");
menu_additem(menu, szLine, szData);
}
menu_additem(menu, "a", "$");
menu_additem(menu, "b", "%");
menu_display(id, menu);
}
