hi, there :)
Consider a blogging application whereby a user is trying to add a new blog. He/she has to select a category. Upon selecting a category from a drop down box, a new sub categories drop down box will be created (hence an AJAX call). Got this implemented and it's ok. Now, let's assume that a given blog can have multiple categories (and subcategories). For example, a blog on a restaurant review can belong to the following categories & subcategories: 1) "food" -> "fine dining" 2) "people" -> "lifestyle" 3) "travelling" -> "restaurants" After selecting a set of category and sub category, there will be a link entitled, "add another category/subcategory" (I guess this can be done with link_to_remote or something). My question is, how do you code it such that upon clicking on the link mentioned, another category drop down box will be displayed in the form. Selecting a category value would then cause a sub categories drop down box to appear in the same form allowing the user to select another sub category. Again, the link entitled, "add another category/ subcategory" will also be shown. How do I go abouts implementing this? I know it's a call to use AJAX but I don't exactly know how. I have tried reading up some rails books and cookbooks to no success. Please help!! :) thanks --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
