Add sorting menu to the Bid Selection screen

See original GitHub issue

Thank you for your help ❤️

What is this project?

DAV (Decentralized Autonomous Vehicles) is a new non-profit foundation working to build an open-source infrastructure for autonomous vehicles (cars, drones, trucks, robots, and all the service providers around them) to communicate and transact with each other over blockchain.

As an organization that believes in building a large community of open-source contributors, we often create issues like this one to help people take their first few steps into the world of open source.


The DAV project you are looking at is Missions. Missions is the client facing side of the marketplace connecting DAV users looking to ship packages, with autonomous vehicles such as drones.

How you can help

The Issue

We want to improve the current ‘Bid Selection’ screen (that appears when ordering a pickup) and allow users to sort the results by price, time of arrival etc., see mockup examples:


The current version does not include the icon to open the sort options, or the sorting options themselves. Both need to be added, as well as the sorting logic itself.

Available sorting options:

  1. Best match - Default selection. A combination of fastest pickup and lowest cost, with preference for fastest pickup (meaning, the items with the fastest pickup will be shown first, and in case of bids with similar pickup time, we’ll show the one with the lowest price first)
  2. Fastest pickup - Sort by the shortest ETA at the pickup location
  3. Fastest delivery - Sort by the shortest ETA at the dropoff location
  4. Lowest cost - Sort by lowest price

UI behaviour:

  • Pressing the sort button on the right hand side will slide the ‘sort by’ menu from the top down
  • The selected choice should be highlighted, accompanied with a green checkmark
  • Selecting a different choice will roll down the menu and refresh the results
  • Pressing on X button will simply roll down the menu (no changes)

See attached zip file with the new icons in svg format:

Re @pfreema1 question in gitter:

@srfrnk Hello! I’m working on DAVFoundation/missions#70. I’ve added the back button functionality, and updated the styling to match the Order Pickup screen, but I noticed that when going back to the Order Pickup screen, the “Set dropoff location” field and the icon select for “How big is the package?” does not persist. Should I make all the data persist when the user clicks back?

I think we can open a new task for that. Hope that answers your question.
