afficher une liste de choix d'une liste sharepoint suivant la valeur d'une colonne

Bonjour

comment faire pour afficher une liste de choix si la valeur de la colonne TOTO de la même list sharepoint est à une valeur X.

Voici le Json de la colonne à afficher :
{
"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
"elmType": "div",
"style": {
"flex-wrap": "wrap",
"display": "flex"
},
"children": [
{
"elmType": "div",
"style": {
"box-sizing": "border-box",
"padding": "4px 8px 5px 8px",
"overflow": "hidden",
"text-overflow": "ellipsis",
"display": "flex",
"border-radius": "16px",
"height": "24px",
"align-items": "center",
"white-space": "nowrap",
"margin": "4px 4px 4px 4px"
},
"attributes": {
"class": {
"operator": ":",
"operands": [
{
"operator": "==",
"operands": [
"@currentField",
"Val3"
]
},
"sp-css-backgroundColor-BgCornflowerBlue sp-field-fontSizeSmall sp-css-color-CornflowerBlueFont",
{
"operator": ":",
"operands": [
{
"operator": "==",
"operands": [
"@currentField",
"Val2"
]
},
"sp-css-backgroundColor-BgMintGreen sp-field-fontSizeSmall sp-css-color-MintGreenFont",
{
"operator": ":",
"operands": [
{
"operator": "==",
"operands": [
"@currentField",
"Val1"
]
},
"sp-css-backgroundColor-BgGold sp-field-fontSizeSmall sp-css-color-GoldFont",
{
"operator": ":",
"operands": [
{
"operator": "==",
"operands": [
"@currentField",
""
]
},
"",
"sp-field-borderAllRegular sp-field-borderAllSolid sp-css-borderColor-neutralSecondary"
]
}
]
}
]
}
]
}
},
"txtContent": "@currentField"
}
]
}

j'ai tenté de jouer sur l'entrée Display mais sans succès.

Merci
