Question

Design:

First Dropdown:

<select id="MainContent_drpVehicleType" style="width:175px;" name="ctl00$MainContent$drpVehicleType">
<option value="">- SELECT -</option>
<option value="1" title="AUTO">AUTO</option>
<option value="2" title="HD">HD</option>
<option value="3" title="MARINE">MARINE</option>
</select> 

Second Drop Down:

<select id="MainContent_drpMake" style="width:175px;" name="ctl00$MainContent$drpVehicleType">
<option value="1" title="ACURA">ACURA</option>
<option value="2" title="ALFA ROMEO">ALFA ROMEO</option>
<option value="74" title="ALLIS CHALMERS LIFT TRUCK">ALLIS CHALMERS LIFT TRUCK</option>
<option value="75" title="ALLIS CHALMERS TRACTOR">ALLIS CHALMERS TRACTOR</option>
<option value="4" title="AMERICAN MOTORS">AMERICAN MOTORS</option
</select>

Code used for execution:

b.select_list(:id, "MainContent_drpVehicleType").select("AUTO")

b.select_list(:id, "MainContent_drpMake").select("ACURA")

and also tried

`b.select_list(:id, "MainContent_drpMake").wait_until_present.option(:text, 'ACURA')`

**What my Problem is able to select "AUTO" from first dropdown and not able to select "ACURA" from second dropdown

Answer 1

It sounds like your second dropdown is populated after the first dropdown value is selected. In that case, you need to wait for the second dropdown list to be populated (rather than for the second dropdown to appear).

You can wait for the specific option to appear and then set it by doing:

#The option element that you want:
option = b.select_list(:id, "MainContent_drpMake").option(:text => "ACURA")

#Wait for the option to appear
option.wait_until_present

#Set the option
option.select

Or if you want to do it on one line, you can use when_present :

b.select_list(:id, "MainContent_drpMake").option(:text => "ACURA").when_present.select
