**As a user,**
**Given** that I am on the “Create a Post ” page
**When** I tap on the “For 1 Month” dropdown menu (By default "For 1 Month" appears).
**Then** a pop up appears with 4 options: A day; A week; A month; Forever
**When** I tap on any of the four options
**Then** the pop up goes back and the change is reflected in the drop down name

**Design:**


**Acceptance Criteria:**
