-### CLAY_ID_LOCAL()
-
-**Usage**
-
-`CLAY(CLAY_ID_LOCAL(char* idString)) {}`
-
-**Lifecycle**
-
-`Clay_BeginLayout()` -> `CLAY(` -> `CLAY_ID_LOCAL()` -> `)` -> `Clay_EndLayout()`
-
-**Notes**
-
-**CLAY_ID_LOCAL()** is used to generate and attach a [Clay_ElementId](#clay_elementid) to a layout element during declaration.
-
-Unlike [CLAY_ID](#clay_id) which needs to be globally unique, a local ID is based on the ID of it's parent and only needs to be unique among its siblings.
-
-As a result, local id is suitable for use in reusable components and loops.
-
-**Examples**
-
-```C
-void RenderHeaderButton(ButtonData button) {
-    CLAY(
-        CLAY_ID_LOCAL("HeaderButton"),
-        CLAY_LAYOUT({ .layoutDirection = CLAY_TOP_TO_BOTTOM, .sizing = { .width = CLAY_SIZING_GROW(0) }, .padding = CLAY_PADDING_ALL(16), .childGap = 16) })
-    ) {
-        // ...children
-    }
-}
-
-for (int i = 0; i < headerButtons.length; i++) {
-    RenderHeaderButton(headerButtons.items[i]);
-}

-### CLAY_IDI_LOCAL()
-
-`Clay_ElementId CLAY_IDI_LOCAL(char *label, int index)`
-
-An offset version of [CLAY_ID_LOCAL](#clay_local_id). Generates a [Clay_ElementId](#clay_elementid) string id from the provided `char *label`, combined with the `int index`. Used for generating ids for sequential elements (such as in a `for` loop) without having to construct dynamic strings at runtime.
