+# `overrides`
+
+Various parts of card configuration may [conditionally](conditions.md) be
+overridden (e.g. to hide the menu in fullscreen mode).
+
+```yaml
+overrides:
+  - conditions:
+       [condition]
+    overrides:
+       [override]
+```
+
+Not all configuration parameters are overriddable, some because it doesn't make
+sense for that parameter to vary, and many because of the extra complexity of
+supporting overriding given the lack of compelling usecases ([please request new
+overridable parameters
+here!](https://github.com/dermotduffy/frigate-hass-card/issues/new/choose)).
+
+Each entry under the top-level `overrides` configuration block should be a list
+item, that has both of the following parameters set:
+
+| Option | Default | Description |
+| - | - | - |
+| `conditions` | | A list of [conditions](conditions.md) that must evaluate to `true` in order for the overrides to be applied. |
+| `overrides` | | Configuration overrides to be applied. Any configuration parameter matching [Overrideable parameters](overrides.md?id=overrideable-parameters) can be overridden. |
+
