How can i move several emails into folders in ipad?

You can not create folders in the Mail App on the iPad. You must do it on the server.

But if you do have folders in your mail account, open the email that you want to move, tap the File Folder Icon (with the arrow pointing down) at the top of the mail window and then you have the option to move that email into any available folder that pops up.

You can sort by using the search feature. When you are in your mail account you use the search bar at the top to find emails from a particular sender (there are Other options as well in search). Type in that sender's address. When the emails show up in the window on the left side, select all of the emails that you want to move. Tap Edit at the bottom and the Move Folder icon will appear. Tap that icon and select the folder that you want to move the emails into.

To move multiple emails without using the search to sort, go to your inbox and tap Edit. Then select all of the emails that you want to move. After you are done selecting them, tap the Move icon at the bottom on the left side of the account window. When you tap move, you get a choice of folder into which you can place the selected emails.

You are quite welcome. Thanks for the award!
