Hi Sunil Kumar,
The following widget from the marketplace will help for multiple selections in the dropdown,
Hope this will help you.
Looking at your requirement, the default datagrid search will already allow you to do that.
Have you tried that. Any problems in using that?
- You can have Text box to filter based on some attribute
- A drop down in filter can have multi-selection option already (https://docs.mendix.com/refguide7/drop-down-search-field#allow-multi-select)
I recomend you to make a microflow that controls the data you recieve in your grid. Place a dataview outside the grid and fill the form with your search parameters.
Instead the dropdown, place a listview with the different options you have in dropdown through an entity. Then, place a checkbox that will contain different options you list in your filter and set a conditional visibility to the checkbox with boolean.
