![[Grasshopper] How to use Shift List to shift data](https://iarchway.com/wp-content/uploads/2025/08/Shift-List.png)
This article explains how to use Shift List to shift data.
On the Grasshopper, it is represented by either of the two above.
Shifting Data
Shift List can be used to shift data.
Input the original data to the Shift List(L).
In this case, a list of 0~9 data is input.
Input the numerical value to be shifted to the Shift List(S).
This time, 3 is input.
Then, as shown in the image above, the first three data are shifted to the bottom of the list.
We changed the value from 3 to 5.
Then, the data is shifted by 5.
In this way, the data can be shifted by the amount of the entered value.
Deleting Displaced Data
The displaced data can also be deleted.
Enter Boolean Toggle in the Shift List(W).
The Boolean Toggle can be toggled between True and False by double-clicking on it.
If the Shift List(W) is not entered, it is initially set to True.
So, entering True will not change it.
If you set it to False, the misaligned values will be deleted.
In the case of the image above, the first three misaligned values are not in the output data.
You can do this without using the Boolean Toggle or by typing the word False.
