-# Customizing FilterableDropdown's search behavior
-
-
-Out of the box, FilterableDropdown does a very simple 'startswith' style lookup to find candidates which match the user's input. However, this behavior can be customized using GooeyOptions to support all kinds of filtering strategies. 
-
-For each example, we'll be starting with the following sample program. This uses just 4 choices to keep the different options easy to follow. However, `FilterableDropdown` is fully virtualized and can be used with 10s of thousands of choices. 
-
-
-```python
-from gooey import Gooey, GooeyParser, PrefixTokenizers
-
-choices = [
-    'Afghanistan Kabul',
-    'Albania Tirana',
-    'Japan Kyoto',
-    'Japan Tokyo'
-]
-
-@Gooey(program_name='FilterableDropdown Demo', poll_external_updates=True)
-def main():
-    parser = GooeyParser(description="Example of the Filterable Dropdown")
-    parser.add_argument(
-        "-a",
-        "--myargument",
-        metavar='Country',
-        help='Search for a country',
-        choices=choices,
-        widget='FilterableDropdown',
-        gooey_options={
-            'label_color': (255, 100, 100),
-            'placeholder': 'Start typing to view suggestions'
-        })
-    args = parser.parse_args()
-    print(args)
-```
