Assembly is extendable and it comes with 15 modules by default, which are:
– Header
– Logo
– Menu
– Container
– Column
– Image
– Title
– Posts
– Comments
– Search Form
– Widgets Sidebar
– Category Filters
– Button
– Social Media
– Map
Those modules allow you to build extremely powerful pages, but if that’s not enough you can add more modules such Gallery, Background Videos, Sliders, Export, and more… clicking on “Assembly” > “Add-ons” or going to loopthemes.com/extensions
When activating the theme for the first time, WordPress will automatically suggest you to activate a few plugins like, Assembly, Assembly Gallery, Assembly Sliders, etc… It is mandatory that you activate those plugins as they are a fundamental part of the theme, without activating those plugins the theme won’t be operative.
