Cascading questions in ODK Build

Hello everyone, I'm using ODK build to build a form for an incoming project and I need your assistance on cascade select. The question is as follows below:

Select an asset class from the options available:

  1. Office equipment
    a. Paper shredder
    b. Water dispenser
  2. Machinery
    a. Planter
    b. Generator
  3. Kitchen equipment
    a. Microwave
    b. Gas cooker
  4. Furniture
    a. Chair
    b. Desk
    c. Table
    d. Cupboard

Kindly assist me on creating this form. Thanks.

It's not clear how you want the cascading select to work? You need 2 questions, with the options shown for the second question dependent on the answer from the first. A classic example is "What state?" and then asking "What city?" but only showing an option list of cities inside of the selected state.

For your example you might have "Select all asset classes" and then asking them to select all items but only showing the item options that match the asset classes they selected.

  1. Select all asset classes:
    Office equipment / Machinery / Kitchen equipment / Furniture

  2. Select all items:
    Paper shredder / Water dispenser / Planter / Generator / Microwave / Gas cooker / Chair / Desk / Table / Cupboard

For example...

  1. Select all asset classes:
    Office equipment
    Machinery
    Kitchen equipment
    Furniture
  2. Select all items:
    Paper shredder
    Water dispenser
    Microwave
    Gas cooker

I think you might need to use XLSForm in order to implement cascading selects.
