Template Engine (Theming)

[Bogdan]

It nice to hear that you separate back-end (admin panel) from user's front-end in versions.

I hope in feature it will be more separated and site templates will not be affected from admin templates. For example, admin panel built on Bootstrap 3 and main site on Bootstrap 4 and it works fine together.

I think now it's time to talk about theme engine. For example, if we using Smarty than navbar file may have a such structure:

PHP Code:

<ul>
{foreach from=$menus item="menu"} 
<li><a href="index.php?p={$menu.link}">{$menu.name} - {$menu.subMenu.link}</a> 
{if $menu.subMenus != ""} 
<ul> 
{foreach from=$menu.subMenus item="subMenu"} 
<li><a href="index.php?p={$subMenu.link}">{$subMenu.name}</a></li> 
{/foreach} 
</ul> 
{/if}</li>
{/foreach} 
<ul> 


So we can design our menu as we want without editing core files. I'm not sure that Smarty is a good engine, but many CMS using it (Prestashop, DLE). Here is the list of theme engines:
