# Freeze Columns
## Three ways to freeze columns
We can freeze columns in many ways. Here is how,
### i. Freeze the column while adding a new one
1. Click on the `+` button to add a new column.
2. Provide column `Name`, `Key name` and rest of the values based on your choice.
3. Check `Frozen?` checkbox for the column.

2. Check the `Frozen?` checkbox.
3. Click on `Save`.

### iii. Freezing column with [Runtime Schema](/features/runtime-schema.md)
We can freeze the column while providing a custom schema too with the `isFrozen` flag in our frontend code.
```javascript
showWidget({
schema: [
{
key: 'email',
name: 'Email',
type: 'Email',
isFrozen: true
}
]
});
```
## Effects on Sample File Generation
The generated sample file will have specified columns freeze on the left side. So they won't gets hidden if we scroll to the right.
