How to make a block stack with overflow?

Question

css

I need it to be like this:

item1	item2	item3
item4	item5

Blocks (namely, block elements) can contain anything (in my case, form fields). The limiter is the width of the form. When there is an overflow, the element should wrap to another line. At first I started to typeset with a regular modular grid, but I got tired of choosing sizes. There are too many elements and they are different in width. Can you tell me how to do it on bootstrap?
Those. not to make explicit table markup (in any way) with rows, columns, etc. And just make one block and throw elements into it.

Answer 1

1) via float: left|right
2) via display: inline-block;
3) via flex + flex-wrap
