Hello, I would like to have plugin which will allow to create website template like here: [login to view URL] Block are made from jpg images, which user can rearrange with drag&drop or arrows. Every image is connected (propobly by file name - see url after sections are selected/rearranged) to saved and uploaded elementor section (json files). When mockup is done, user click "download template" button, and gets one combined json file with entire template created from selected sections in the correct order, ready to be imported into the elementor. On [login to view URL] page there are only one level of categories (hero, about us, features etc). I would like to have categories and subcategories. On the top there should be dropdown with main categories like: Show All - default - shows all sub-categories Home page Contact Page Product Page Landing Page Blog Archive Single Blog Page Etc there should be place in code to assign main category to symbol (number value). Something like: homepage -> 1 Contact Page -> 2 Product Page -> 3 etc I would like to use it to add new and change names of present categories. When main category is selected subcategories should appear below. Sub categories are those seen on [login to view URL] (hero, about us, features, etc) I would also like to assign subcategory to symbol (single letter): hero -> a about us -> b features -> c etc I would like to use it to add new and change names of present sub-categories. Every subcategory CAN be available in few categories. For example "hero" subcategory can be picked from homepage, product page or landing page. Connections between categories and subcategories can be coded in every sections file name. [login to view URL] means that this hero section (section from subcategory "a") is avaiable in contact page ("2") and home page ("1") category. [login to view URL] means that this hero section (section from subcategory "a") is available in product page ("3") category. Inside WP uploads folder there should be created new folder for this plugin which will contain all json and jpg files. Json file of given section which will be used to generate final json template, and jpg file with the same name which will be used in app to build template. Rest functions should be similar to [login to view URL]: drag and drop, moving block up and down, zoom in and out, possibility to delete single section or everything at once. And last function is random template. I would like to make it work like that: 1. user chooses main category. 2. user click "random template" button 3. app takes one random section from every subcategory of this category (in asc order of assign symbols from a to z) and puts it on design canvas. Then if user is logged in he can click "create template" button and combine selected section json files into one final json file which he can import to his elementor page. If he is logget out there should be alternative, button to redirect to login page.
