I've expanded the size of the Start Menu so I can put a lot of Tiles there, but when I drag a Tile to a new location it sometimes bounces back to where it had been. Other times moving a Tile somewhere will cause another Tile so shift to somewhere else.
How can I instruct the Start Menu to allow me to place (by dragging) any Tile anywhere I want?
The Windows 10 Start Menu is not a desktop. It is actually a series of square grids grouped under headings (called groups). When you move a tile to an empty group, you can see the space for the heading for that group appear. It seems to be a limitation that the spaces directly below a foup heading must be filled first. You can drag a tile to the third or fourth row under a group heading without the row above it being occupied by at least one tile first.
There can only be one tile in each grid space, so when you try to place a tile over the top of an existing one, the previously existing tile there must be moved out of the way for the new tile to fit in that grid space. The previous tile is moved to the nearest empty grid space underneath the same group heading.
If you click in the space for the group heading you can enter a name for that group. See this thread for an example:
