+
+### ColorMapLike objects
+
+Colormaps may be specified in a variety of ways, such as by name (string), an iterable of a color/color-like objects, or as
+a [`cmap.Colormap`][] instance. See [cmap documentation for details on
+all ColormapLike types](https://cmap-docs.readthedocs.io/en/latest/colormaps/#colormaplike-objects)
+
+### Example
+
+```python
+from cmap import Colormap
+from qtpy.QtWidgets import QApplication
+
+from superqt import QColormapComboBox
+
+app = QApplication([])
+
+cmap_combo = QColormapComboBox()
+# see note above about colormap-like objects
+# as names from the cmap catalog
+cmap_combo.addColormaps(["viridis", "plasma", "magma", "gray"])
+# as a sequence of colors, linearly interpolated
+cmap_combo.addColormap(("#0f0", "slateblue", "#F3A003A0"))
+# as a `cmap.Colormap` instance with custom name:
+cmap_combo.addColormap(Colormap(("green", "white", "orange"), name="MyMap"))
+
+cmap_combo.show()
+app.exec()
+```
+
+{{ show_widget(200) }}
+
+### Style Customization
+
+Note that both the LineEdit and the dropdown can be styled to have the colormap
+on the left, or fill the entire width of the widget.
+
+To make the CombBox label colormap fill the entire width of the widget:
+
+```python
+from superqt.cmap import QColormapLineEdit
+cmap_combo.setLineEdit(QColormapLineEdit())
+```
+
+To make the CombBox dropdown colormaps fill
+less than the entire width of the widget:
+
+```python
+from superqt.cmap import QColormapItemDelegate
+delegate = QColormapItemDelegate(fractional_colormap_width=0.33)
+cmap_combo.setItemDelegate(delegate)
+```

+# QSearchableTreeWidget
+
+`QSearchableTreeWidget` combines a
+[`QTreeWidget`](https://doc.qt.io/qt-6/qtreewidget.html) and a `QLineEdit` for showing a mapping that can be searched by key.
+
+This is intended to be used with a read-only mapping and be conveniently created
+using `QSearchableTreeWidget.fromData(data)`. If the mapping changes, the
+easiest way to update this is by calling `setData`.
+
+
+```python
+from qtpy.QtWidgets import QApplication
+
+from superqt import QSearchableTreeWidget
+
+app = QApplication([])
+
+data = {
+    "none": None,
+    "str": "test",
+    "int": 42,
+    "list": [2, 3, 5],
+    "dict": {
+        "float": 0.5,
+        "tuple": (22, 99),
+        "bool": False,
+    },
+}
+tree = QSearchableTreeWidget.fromData(data)
+tree.show()
+
+app.exec_()
