I have to create such a functionality where I have to show a search bar using which CA can drag and drop the document into interface. And the dragged documents should be put in a grid having delete icon besides them. How can I achieve this functionality in Appian interface.

For the first part https://docs.appian.com/suite/help/23.4/Document_Browser_Component.html try this (somewhat it reaches your requirement) for second part use "Richtext Display field in grid column" with submit link .
