我有一个无序列表：
<ul class="list_arrow2">
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Signup Options </span>– Describe your signup options
that an applicant can choose from. List the signup option type,
description, and price. For example, the two signup options might be
Customer or Distributor; each option would carry a different description
of cost and details.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Order Options </span>– Indicate any additional purchase
options that an applicant may have. This may be in the form of a single
item or package item order. For example, you might want to give the
applicant a choice to purchase a "starter kit" that includes various
products that you sell. Be sure to list the details of these items,
including a description and price.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Autoship Options </span>– This section can be exclusive
of the Order Options section or you can include both. The Autoship
section is just like the Order Options section except that the applicant
is agreeing to receive the order on an monthly, recurring basis. Be
sure to include descriptions, pricing, etc.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Payment Options </span>– List the types of credit cards
you accept (Visa, M/C, AMEX, Diners). Also, if you intend on taking
personal checks online, or ACH, be sure to add this to your details.
If you plan on taking online checks, or ACH, please contact your Account
Manager for more details on getting this set up.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Terms and Conditions</span>– Please provide the full text
of your terms and conditions and/or Distributor Agreement. This will
be displayed for the applicant to agree to before proceeding with
their registration.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Confirmation Message </span>– Please provide us with
the text that is displayed once the applicant successfully signs up.
This text is also emailed to the new applicant.
</li>
<li>
<span style="display: inline-block; width: 150px; font-weight: bold;">
Welcome Message </span>– Please provide us with the text
that is displayed as an introduction to the applicant.
</li>
</ul>
现在，如果文本溢出到下一行，它将一直向左对齐（例如在订单选项下的右侧）。保持列表标题（订单选项）与左侧对齐的最佳方法是什么，以及描述订单选项的文本是否溢出到下一行以与其自身对齐？
订单选项 - 这是一些文本
我在流动的文字上很丑
订单选项 - 这是一些文本
我的文字很溢出！
