<tree>可以加上文字屬性跟顏色

<tree decoration-bf="customer_rank &gt;0"
        decoration-danger="customer_rank &gt;0 and supplier_rank &gt;0"
        decoration-warning ="supplier_rank &gt; 0">
    <field name="name"/>
    <field name="user_id" widget="many2one_avatar_user"/>
    <field name="state_id" optional="hide"/>
    <field name="country_id" optional="show"/>
    <field name="customer_rank" invisible="1"/>
    <field name="supplier_rank" invisible="1"/>
</tree>

※decoration-bf為粗體、decoration-danger顯示紅色、decoration-warning顯示黃色

<Search>通常使用三種寫法

會在搜尋欄位出現name、category_id、bank_ids來做為搜尋的依據:

<search>
    <field name="name"/>
    <field name='category_id" filter_domain="[('category_id','child_id','self')]"/>
    <field name="bank_ids" widget="many2one"/>
</search>

會在Filters裡面作用，以Suppliers作為過濾的依據:

<search>
    <filter name="suppliers" string="Suppliers" domain="[('supplier_rank', '>', 0)]"/>
</search>

會在Group By裡面作用，以Conutry作為分組的依據:

<search>
    <group expand="0" string="Group By">
        <filter string="Country" name="country" context="{'group_by':'country_id'}"/>
    </group>
</search>

#### ※可以加入這段來使的畫面出現左邊分類工具欄
```CMD
<searchpanel>
    <field name="user_id" icon="fa fa-users"/>
    <field name="category_id" icon="fa fa-list" select="multi"/>
</searchpanel>

form_view_ref與tree_view_ref可以指定開啟的view

<field name="context">
    {'tree_view_ref':'my_module.tree_all_contants'}
</field>
