What are PHP Frameworks for HTML (POST) Form Rendering and Processing?

I am new to PHP and a standard task in HTML Development is Form Rendering & Processing. What are PHP Frameworks that support the following requirements:

• Declarative Definition of Form elements with
  
  
  
  • Optional: Declarative Validation/Sanitization Definition
  
  
  • Optional: Help (Icon/Poup)
  
  
  
  


• Easy to define/create own custom / composite Elements


• Support of Repeatable Fields
  
  
  
  • (You define a group of elements that a user can add a lot of instances like an address1, address2…)
  
  
  
  


• Processing of the incoming POST Data
  
  
  
  • Including Validation, Sanitization based on definition
  
  
  
  


• Not Pure JS based (at least the form should render and be submittable without JS turned on/gracefull fallback)


• Responsive


• Stateless


• Ideally a large repository of ready elements
  
  
  
  • Standard HTML Input elements
  
  
  • additionally for example: tree-select, map, date/time, wysisyg editor, upload with preview, slider….)
  
  
  
  

I came across CMB2 (but this is something more for Wordpress and has some drawbacks…). As I am new to PHP I am looking for something like this for PHP in general. (in Some extend its like Java Server Faces, but no State oriented or real Component Framework only something lightweight). I could implement this on my own, but even using thirdparty libs for Help, Validation etc… doing this right will be much beyond 5000 LOC and would be a waste of time if there are good frameworks that do this already.
