What is the best way to organize the structure?

Question

Yii

Hello. I am learning yii in the process of developing my site, now I need to make a category page, to be more precise, this should be the page on which I will display the definition. goods according to letters, there should be several such filter pages (categories), here is an image of what I need, i.e. I go to op. I press any letter on the page and I should be shown a list of products in which the first letter of the name matches.

so I created an alphabet search page, made a controller and a view, for filtering by model I used the same controller as for the alphabet, only the action was specified differently (I redirect through urlManager), then I plan to do other pages in the same way, through one controller everything , I do this because further it will be necessary to automatically create dynamic categories, for this reason I decided to combine everything into one controller, but I doubt something is correct, please tell me what is the best way ?, all that is static divided into separate controllers, etc., and the rest can be combined.

Answer 1

You need 2 controllers.
One creates a letter selection page and checks if the user has selected a letter.
The second one checks the selected letter and returns items starting with that letter.
And to be without reloading, renderAjax is used
