Post creation - choose tag

[helenebar]

AS a user,
Given that I am on the "Create the post" page
When I tap on the "Add a tag"
Then a pop up appears with a list of tabs (refer to the design to see all the tags)
When I select a number of tags
Then the Add tags buttons show the number of tags I have selected
When I have selected at least 1 tag and tapped on the "Add x tags" button
Then I am back on the main page and the "Add tag" is minimized to a + sign
