Updated those changes and created pull request.

• Checked on Chrome and Firefox using test instance;

• The administrator ‘Data Export’ page which manages data export functionality is created;

• The page contains two dropdowns.

Issues found:

1. We should rename the files in the Data drop-down:

• Orderable.csv → orderable.csv

• OrderableIdentifier.csv → orderableIdentifier.csv

• ProgramOrderable.csv → programOrderable.csv

• TradeItem.csv → tradeItem.csv

2. After selecting the checkboxes, the files names fill up in the Data field, but doesn’t contain the format. We should rename the files names, displaying in the Data field:

• orderable → orderable.csv

• orderableIdentifier → orderableIdentifier.csv

• programOrderable → programOrderable.csv

• tradeItem → tradeItem.csv

3. The background is expanding after selecting the Data field. It should be sticked, as in the e.g. creating roles modal.
