<template>
    <template v-slot:form="{ item }">
        <el-row v-for="(dishesIngredient, index) in parArr" :key="index">
          <el-form-item :label="'原料'+(index+1)" :prop="'data.ingredients.'+index+'.ingredientId'" :rules="{required: true, message:'原料不能为空', trigger: 'blur'}">
            <el-select v-model="dishesIngredient.ingredientId" clearable :placeholder="`请选择原料`" @change="handleIngredientListChange($event, index)">
              <el-option v-for="ingredient in ingredientList" v-show="dishesIngredient.ingredientId == ingredient.ingredientId || !selectIdsArr.includes(ingredient.ingredientId)" :key="ingredient.ingredientId" :label="ingredient.ingredientName" :value="ingredient.ingredientId" />
