The items of ZUL Palette are hard to select due to focus automatically to the first drawer. When you click on the desired item, it would not be selected but the first drawer (ZK Element).

Please see the attached gif for detail.

It is okay on Juno, Kepler and Luna. Affected on Mars, Neon and Oxygen.

Steps to Reproduce

1. Install ZK Studio 2.0.1 on Eclipse Neon or Oxygen
2. Create a new ZK Project or ZUl file
3. Use the ZUL Palette, expand any drawer and hover on the items
4. Click the item text

Current Result

1. The "ZK Element" drawer will get the foucs and be expanded
2. The item you clicked will not be selected

Expected Result

1. The "ZK Element" drawer will not get the foucs and be expanded
2. The item you clicked will be selected

Workaround

1. Use Eclipse Luna (<= 4.4)
2. Use icons only layout
3. Click the icon instead of the text

Debug info

The first drawer will be selected only if you hover on the item text.
Hover on the icon (or use icons only layout) is okay.
