    <p>Good day,</p> <p>This is more web service design than programming question I think. I'll try to explain what I want to achieve. In example I have a 3 combo boxes(e.g. size, color, texture) on the page which are dependent on each other. We can select them only in turns(eg. 1st->2nd->3rd). After selecting combo box value, next combo box gets populated+enabled and we are able to select from it too.</p> <p>I came up with a few solutions which I can apply for this problem.</p> <ol> <li>Is when we come to the page and loaded JavaScript sends a post with a request for data to populate those combo boxes. The response returned is a batch data of all variants(JSON) is parsed and handled by JavaScript with every selection client does.</li> <li>Page is loaded with only first combo box and the remaining ones gets filled with the default values. Every time client selects a value, appropriate event(ajax which leads to post get) is fired to fill/handle next combo boxes dependent on selections.</li> </ol> <p>Myself I see that first one is quite complicated and the batch value can be very big in terms if there are lots of selection variations for each of the value. And the second one seems does too many useless requests to the server which I think can lead to server overload. What do you think of these solutions? Does the concept is okey? And is it worth to implement first solution instead of second one even it is harder? If something you do not understand in my explanation please ask I'll try to explain in more detail.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
