Is it possible to create dynamic select?

[yingliangzhang]

Hi,

Just wondering is there a way to create a dynamic select, or in other words a select that depends on another select's selected value?

For example, I have a "Category" select and a "SubCategory" select, the sub-categories should be dynamically loaded depends on what Category is selected.

FormItem::select('category_id', 'Category')->list(\App\Category::class);
FormItem::select('sub_category_id', 'SubCategory')->list(\App\SubCategory::class);

But now the SubCategory select knows nothing about the Category. Can I pass in parameters to the list() method, such as category_id to retrieve the sub-category list?
