VUEJS：使用输入和复选框过滤数据

Question

我想使用输入和复选框过滤我的数据。以下是您可以看到但无法正常工作的代码脚本。根据脚本；当未在输入字段中输入文本时，即使检查了复选框，即使检查它们也无法正常工作。我在哪里做错了？

<input v-model="search_all_task">

<input type="checkbox" class="form-check-input" true-value="title1" false-value="" v-model="dashSelect3" @id="dashSelect1 = $event.target.value" id="checkbox1">
<label class="form-check-label" for="checkbox1">Title 1</label>

<input type="checkbox" class="form-check-input" true-value="title2" false-value="" v-model="dashSelect3" @id="dashSelect2 = $event.target.value" id="checkbox2">
<label class="form-check-label" for="checkbox2">Title 2</label>

<input type="checkbox" class="form-check-input" true-value="title3" false-value="" v-model="dashSelect3" @id="dashSelect3 = $event.target.value" id="checkbox1">
<label class="form-check-label" for="checkbox1">Title 3</label>

data() {
   return {
     allTaskDashboard : [
           { id: 1, title: "title1", content: "content1" },
{ id: 2, title: "title2", content: "content2" },
{ id: 3, title: "title3", content: "content3" }
       
       ]
 }
},
computed:{
   filterDashboardTask(){

      return this.allTaskDashboard.filter(item =>{
         return(
            this.search_all_task.length === 0 || item.content.toLowerCase().includes(this.search_all_task.toLowerCase())
            || this.dashSelect2.includes(item.title) 
            || this.dashSelect1.includes(item.title)
            || this.dashSelect3.includes(item.title)
            ) 
      });
   },
}

<div v-for="item in filterDashboardTask">
// This another parametres
</div>
