What are the requirements in order to not do Borer? Is there a way, for example, to organize a pile of toys or clothes?

 

If something is mixed together with another thing, like toys or clothes, it is אסור to separate one from another to sort each one and organize. However, if the toys are all over the room and there is space between one toy and another, and it is not mixed together, then it is okay to put each one back in their proper place. The reason being since you are not separating one from another, because they were already separate beforehand.

There are opinions that allow one to intently throw all the toys up in order for it to separate by itself and afterwards to put them away.
