Risk/Return [Heading]	rr_RiskReturnHeading	Coldstream Dividend Growth Fund
Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Coldstream Dividend Growth Fund (the "Fund") seeks dividend income while maintaining exposure to the market.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold No Load shares of the Fund.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	SHAREHOLDER FEES (fees paid directly from your investment) None
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 56.12%.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text]	rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees	Total Annual Fund Operating Expenses do not correlate to the Ratio of Expenses to Average Net Assets Before Advisory Fee Waiver in the Financial Highlights section of the statutory prospectus, which reflects the operating expenses of the Fund and does not include the 0.01% attributed to acquired fund fees and expenses ("AFFE").
Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (taking into account the Expense Cap only in the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund will, under normal circumstances, invest at least 80% of its net assets in dividend-paying common stocks. The Fund invests primarily in the common stocks of domestic large capitalization companies with market capitalizations above $10 billion that have strong growth potential and attractive dividend and yield opportunities. The Fund may also hold American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs") of non-U.S. companies in an amount of up to 20% of the Fund's net assets. Additionally, the Fund may invest up to 15% of its net assets in publically traded Master Limited Partnerships ("MLPs").    The Advisor employs a "bottom-up" strategy in developing the Fund's portfolio and targets 35 to 45 individual stock holdings. The Advisor selects securities for investment based upon proprietary screens that combine both fundamental and technical analysis. Each stock considered for purchase must have: (i) a current yield of at least 1.6%, (ii)  five-year earnings growth of at least 5% per year, (iii)  five-year dividend growth of at least 3.5% per year, and (iv) a strong financial profile. While these are minimum requirements, the Advisor seeks companies that are expected to grow their annual dividend at a double digit rate. Once these fundamental requirements are met, each stock is subjected to a series of technical screens to determine whether or not there is adequate market sponsorship for the company. If a security passes both the fundamental and technical screens, then it is subjected to a thorough price analysis. The Advisor uses a disciplined process to attempt to ensure that securities are purchased at a favorable price. Factors considered include price/earnings ("P/E") growth ratio, current P/E, historic P/E, moving average price, sector strength, sector multiples and changes in expected future earnings. The Advisor may also consider other factors as it deems appropriate. Sector allocation is a residual of the stock selection process and portfolios may not be diversified across all sectors. The Fund may from time to time emphasize investments in certain sectors of the market. The Fund's strategy strives to reduce volatility by limiting individual position sizes to 5% of the Fund's total assets and by limiting single industry exposure to less than 25% of the Fund's total assets. Target prices are developed for each security, but the Advisor does not have a strict sell discipline. The Advisor believes that in times of extreme market volatility, a strict sell discipline would require wholesale liquidations resulting in extremely large cash positions. Under most circumstances, the Advisor will not hold cash positions in excess of 15% of the Fund's net assets in order to maintain participation in growth opportunities in the overall market but will consider cash positions in excess of this threshold under certain market or economic conditions.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Fund. The following additional risks could affect the value of your investment: ·  Management Risk - If the Advisor's investment strategies do not produce the       expected results, the value of the Fund would decrease.                        ·  Market Risk - Either the stock market as a whole, or the value of an              individual company, goes down resulting in a decrease in the value of the         Fund.                                                                             ·  Master Limited Partnership Risk - Investments in securities (units) of MLPs       involve risks that differ from an investment in common stock. To the extent       that an MLP's interests are all in a particular industry, the MLP will be         negatively impacted by economic events adversely impacting that                   industry. Additionally, holders of the units of MLPs have more limited control    and limited rights to vote on matters affecting the partnership. There are        also certain tax risks associated with an investment in units of MLPs.            ·  Sector Risk - To the extent the Fund invests a significant portion of its         assets in the securities of companies in the same sector of the market, the       Fund is more susceptible to economic, political, regulatory and other             occurrences influencing those sectors.                                            ·  Foreign Securities Risk - Foreign securities can be more volatile than            domestic (U.S.) securities. Securities markets of other countries are             generally smaller than U.S. securities markets. Many foreign securities may       also be less liquid than U.S. securities, which could affect the Fund's           investments.                                                                      ·  Investment Style Risk - The Fund's investments in dividend-paying common          stocks may cause the Fund to underperform funds that do not limit their           investments to dividend-paying common stocks during periods when                  dividend-paying stocks underperform other types of stocks. In addition, if        stocks held by the Fund reduce or stop paying dividends, the Fund's ability to    generate income may be affected.
