Per impostazione predefinita, la richiesta One Tap viene visualizzata nell'angolo in alto a destra delle finestre del browser web per computer. Quando viene utilizzato FedCM, il browser controlla completamente la posizione della richiesta. Pertanto, i layout personalizzati non sono supportati.
In caso contrario, mostra One Tap all'interno di un elemento contenitore per modificare la posizione del prompt.
Per farlo, specifica l'ID DOM dell'elemento container
nell'attributo data-prompt_parent_id.
Il seguente esempio di codice riutilizza l'elemento g_id_onload come elemento contenitore e mostra la richiesta One Tap nella posizione specificata:

Custom positions are not supported. For new One Tap integration, you shouldn't customize the prompt's position. For existing integration, review the [migration guide](/identity/gsi/web/guides/fedcm-migration#layout) and update your app if necessary.\n| **Objective:** If the default login flow doesn't meet your requirements, you can customize it in several ways. Read the following information for available customization options.\n\nBy default, the One Tap prompt is displayed in the top-right corner of desktop\nweb browser windows. When [FedCM](/identity/gsi/web/guides/supported-browsers#compatibility) is used, browser fully controls the\nprompt location. Hence, custom layouts are **not** supported.\n\nOtherwise, display One Tap inside a container element to change prompt position.\nTo do so, specify the DOM ID of the container element in the\n`data-prompt_parent_id` attribute.\n| **Warning:** Don't hide any One Tap prompt content. Don't obscure the perception that the One Tap prompt content is from a Google iframe. Failure to do so may result in project suspension, account suspension, or both.\n\nThe following code example reuses the `g_id_onload` element as the container\nelement and displays the One Tap prompt in the specified position: \n\n \u003cdiv id=\"g_id_onload\"\n data-client_id=\"\u003cvar translate=\"no\"\u003eYOUR_GOOGLE_CLIENT_ID\u003c/var\u003e\"\n data-login_uri=\"\u003cvar translate=\"no\"\u003ehttps://your.domain/your_login_endpoint\u003c/var\u003e\"\n data-prompt_parent_id=\"g_id_onload\"\n style=\"position: absolute; top: 100px; right: 30px;\n width: 0; height: 0; z-index: 1001;\"\u003e\n \u003c/div\u003e\n\nThe `data-prompt_parent_id` attribute is ignored on mobile web browsers."]]
