+## Selecting table controls
+
+Use DataTables' [`dom` option](https://datatables.net/reference/option/dom)
+to select the elements of the table that should be displayed:
+- `l`: length changing input control
+- `f`: filtering input
+- `t`: The table!
+- `i`: Table information summary
+- `p`: pagination control
+- `r`: processing display element
+
+For instance, if you don't want the search box, the length input control and the table summary, use
+
+```{code-cell}
+import pandas as pd
+
+show(pd.DataFrame({"a": [2, 1]}), dom="tpr")
+```
+
+Note: you can change the default value of the dom option by setting `opt.dom` as in the examples below.
+
 ## Row sorting
 
 Select the order in which the row are sorted with the [datatables' `order`](https://datatables.net/reference/option/order) argument. By default, the rows are sorted according to the first column (`order = [[0, 'asc']]`).
 
 If you want to deactivate the sorting, set `order = []`, either in the `show` method, or as a global option:
 
 ```{code-cell}
-import pandas as pd
 import itables.options as opt
 
 opt.order = []  # no sorting

 **Added**
 - `itables.options` and the `show` function have a new `column_filters` argument to display individual column search boxes ([#69](https://github.com/mwouts/jupytext/issues/69))
+- We have documented DataTables' `dom` option.
 - We have introduced a new class `JavascriptFunction` to limit the evaluation of Javascript function to selected ones.
 - The documentation is formatted with `black` thanks to a Jupytext & Black pre-commit hook.
