You just need to make up two tablets.
In Table 1, there will be some values: for example, Value 1, Value 2, Value 3, etc.
Table 2 will be empty.
The table will be on one line. Between them there will be 2 buttons:
1) ">"
2) "<"
Accordingly, if a value is selected in the first table and the ">" is pressed, the value should flow into the second table.
Question: how best to do it?
